Because its a different tool. its a different kind of lens.... just because the 10-17 covers the same focal range doesnt not mean its comparable to an ultra wide angle. I already have a 10-22 as well. So n00bs quit suggesting i buy a ultra wide when I AM LOOKING FOR A FISHEYE!

lots of good reviews. from anyone i have heard use it. plus FM reviews has 9.2 rating

I just don't see very good reviews for Tokina's other lenses besides the 12-24 so I wasn't sure. it is a very interesting lens to say the least...I need to do more research on it before I think about getting the Nikon 10.5mm
